Founded in 1994, Science Club for Girls fosters excitement, confidence, and literacy in STEM (science, technology, engineering and mathematics) for girls, young women, and gender expansive youth from underrepresented communities with free, experiential community-based programs. With women making up less than 26 percent of the STEM workforce—and Black and Hispanic women at less than 4 percent—SCFG addresses a critical need, offering a continuum of engaging activities in STEM for K-8 girls, junior mentoring and leadership experiences for high school girls, and adult mentoring and role modeling by committed women with STEM careers. Over the last 13 years, over 90% of our high school juniors and seniors have gone on to college, with over 55% of our graduates majoring in STEM.
